Product Overview
2000V PV Wire yog engineered rau tiam tom ntej ntawm siab -voltage photovoltaic system architecture. Raws li kev lag luam hnub ci txav mus rau 1500V DC thiab dhau mus, cov txheej txheem rwb thaiv tsev ntawm cov hlau yuav tsum ua kom nrawm. Standard 600V lossis 1000V PV hlau tsis tuaj yeem siv rau hauv cov tshuab tsim los saum toj no nws qhov ntsuas hluav taws xob, thiab nrog kev siv hluav taws xob- cov phiaj xwm loj zuj zus ntxiv siv 1500V txoj hlua tsim, 2000V- ntsuas hlau muab ob qho tib si cov txheej txheem rwb thaiv tsev thiab lub taub hau rau kev hloov pauv hauv lub neej yav tom ntej. Qhov no tsis yog ib qho tuab tuab ntawm cov qauv PV hlau. Cov txheej txheem rwb thaiv tsev, phab ntsa tuab, thiab kev ua haujlwm dielectric tshwj xeeb yog tsim los tiv thaiv kev ua haujlwm tsis tu ncua ntawm 2000V DC.

Vim li cas 2000V Rating Matters
Kev hloov ntawm 1000V rau 1500V DC txoj hlua tsim yog ib qho tseem ceeb tshaj plaws hauv kev siv hluav taws xob- teev hnub ci. Cov hlua ntev dua txhais tau tias tsawg dua kev sib txuas, tsawg dua tooj liab, thiab qis dua - ntawm - tus nqi system. Tab sis qhov kev hloov no kuj txhais tau hais tias cov xaim yuav tsum raug ntsuas rau qhov siab dua, thiab NEC xav kom cov kab hluav taws xob ntsuas hluav taws xob sib ntsib lossis tshaj qhov siab tshaj plaws qhov hluav taws xob, suav nrog qhov txias - qhov kub thiab txias qhib - kho qhov ntsuas hluav taws xob.
Hauv kev xyaum, 1500V DC system tuaj yeem tsim qhib- qhov hluav taws xob hluav taws xob mus txog 1600-1700V nyob rau hauv cov xwm txheej txias. A 2000V-rated xaim muab cov npoo zoo siab tshaj qhov theem no, ua kom muaj kev ua raws cai yam tsis tas yuav tsum tau muaj kev pom zoo tshwj xeeb engineering. Nws tseem tso cai rau kev teeb tsa rau yav tom ntej muaj peev xwm nce hauv qhov system voltage raws li inverter thiab module technology txuas ntxiv mus.
Core siv
1500V DC Txoj hlua hluav taws xob
Thawj daim ntawv thov. Hauv kev siv hluav taws xob- nplai thiab kev lag luam loj tsim ntawm 1500V DC, txhua tus neeg xyuas pib hauv PV qhov chaw yuav tsum muaj qhov ntsuas 2000V. Qhov no suav nrog cov hlua hlau, cov khoom siv hluav taws xob hauv tsev, thiab txhua qhov txuas txuas ntxiv hauv qhov siab -voltage DC seem ntawm qhov system.
High-Voltage Combiner thiab Feeder Circuits
Combiner outputs thiab DC feeder khiav hauv 1500V systems kuj xav tau 2000V- ntsuas hlau. Qhov ntsuas hluav taws xob siv rau tag nrho DC Circuit Court, tsis yog txoj hlua - theem conductors.
Yav tom ntej -Nyob Infrastructure
Qee qhov project developers qhia 2000V xaim txawm nyob rau hauv tam sim no 1000V systems kom tsis txhob rewiring yog hais tias lub site yog tom qab upgraded rau 1500V architecture. Qhov kev mus tom ntej no- saib mus kom ze ntxiv tus nqi tsawg kawg ntawm lub sijhawm teeb tsa thiab tuaj yeem txuag tau cov nuj nqis tseem ceeb yog tias muaj qhov hloov pauv hluav taws xob tshwm sim thaum lub sijhawm ua haujlwm.
Daim ntawv thov Scenario
Kev siv hluav taws xob-Sale Solar Farms
Loj hnub ci ua liaj ua teb ua haujlwm ntawm 1500V DC sawv cev rau lub lag luam tseem ceeb rau 2000V PV Hlau. Cov haujlwm no siv cov hlua ntev dua nrog ntau cov qauv hauv cov koob, ua kom qhib siab dua - qhov hluav taws xob hluav taws xob uas xav tau kev ntsuas hluav taws xob zoo dua. Txhua txoj hlua hluav taws xob, kev khiav haujlwm hauv tsev, thiab cov khoom sib txuas tso tawm hauv ntu DC siv 2000V- ntsuas cov xaim kom tau raws li NEC cov cai.
Kev lag luam loj nrog 1500V Inverters
Raws li 1500V hlua inverters dhau los ua muaj nyob rau hauv cov qauv me me, kev lag luam loj ru tsev thiab carport systems tau pib txais siab -voltage DC architecture. 2000V PV Wire ua rau cov kev teeb tsa no txhawm rau ntes BOS tus nqi txuag ntawm 1500V tsim thaum tuav tag nrho cov cai ua raws.
Hnub Ci Ntxiv Cia Nrog Siab -Voltage DC Bus
Qee qhov chaw cia khoom siab heev siv siab -voltage DC coupling ntawm PV array thiab roj teeb. Thaum lub tsheb npav DC voltage tshaj 1000V, txhua tus neeg xyuas pib hauv qhov siab -voltage seem yuav tsum tau 2000V- cov xaim ntsuas kom tau raws li kev nyab xeeb thiab cov cai.
Xaiv Phau Ntawv Qhia
2000V PV Hlau yog yuav tsum tau nyob rau hauv tej PV system qhov twg lub siab tshaj plaws system voltage tshaj 1000V DC. Qhov no suav nrog tag nrho 1500V DC txoj hlua tsim tom qab siv NEC txias - qhov kub thiab txias kho qhov ntsuas kub.
Rau cov tshuab ua haujlwm ntawm 1000V DC lossis qis dua, tus qauv 1000V- ntsuas PV hlau yog txaus. Txawm li cas los xij, kev qhia txog 2000V xaim nyob rau hauv 1000V system muab kev hloov kho tshiab rau yav tom ntej ntawm tus nqi qis dua.
